In oxygen (O2) limiting environments, numerous aerobic bacteria have the ability to shift
from aerobic to anaerobic respiration to release energy. This process requires alternative …

In oxygen-limited environments, denitrifying bacteria can switch from oxygen-dependent
respiration to nitrate (NO3−) respiration in which the NO3− is sequentially reduced via nitrite …

The complex aggregation of bacteria flocs (bioflocs) plays a vital role in the inorganic
nitrogen transformation process within biofloc systems. However, few reports have focused …

The ability of Geobacter species to transfer electrons outside cells enables them to play an
important role in biogeochemical and bioenergy processes. Our knowledge of the …

Denitrification consists of the sequential reduction of nitrate to nitrite, nitric oxide, nitrous
oxide, and dinitrogen. Nitrous oxide escapes to the atmosphere, depending on copper …

The alkaliphilic bacterium Pseudomonas pseudoalcaligenes CECT5344 uses free cyanide
and several metal− cyanide complexes as the sole nitrogen source and tolerates high …

Through complex interspecies interactions, microbial processes drive nutrient cycling and
biogeochemistry. However, we still struggle to predict specifically which organisms …

Small RNAs have been studied in detail in domains Bacteria and Eukarya but, in the case of
the domain Archaea, the knowledge is scarce and the physiological function of these small …

Global atmospheric loading of the climate-active gas nitrous oxide (N2O) continues to
increase. A significant proportion of anthropogenic N2O emissions arises from microbial …

The regulatory networks involved in the uptake and metabolism of different nitrogen sources
in response to their availability are crucial in all organisms. Nitrogen metabolism pathways …
